Description

The invention relates to a system for selecting and accounting for the shipment of liquid products with redundancy, in particular to systems for supplying light petroleum products for loading in devices for selecting and commercial metering for the shipment of petroleum products on racks of railway gallery or clock loading, automobile loading.

On racks of railway gallery or clock loading, automobile loading during shipment of liquid petroleum products, according to existing regulatory documents, systems are provided for selecting and commercial accounting for shipment of one or more types of products.

A typical design is a measuring system containing a unit for shipping oil products on racks for automobile or railway transport for selecting and accounting for the shipment of more than one type of oil products, containing bulk risers, liquid meters, shut-off valves, liquid filters, pump units, and the unit hydraulics can be equipped with a densitometer, a temperature sensor, a gas separator, a modulating shut-off valve and a drainage system, for example, according to utility model RU 28682 U1, published on 04/10/2003. In the known measuring complex, measuring means for metering the flow are located in each of the individual pipelines for supplying each type of product to the bulk line, made in the form of a bulk riser (see figure 3 RU 28682 U1). A gas separator is installed in front of each measuring device to account for the flow rate to prevent the ingress of undissolved gases. At the highest point of the bulk riser is an air valve. This system is made with the ability to dispense through one bulk riser from one to two types of products without mixing them by providing natural emptying of the mains of the bulk riser and the space after the collector at each product change.

A disadvantage of the known solution is the need to install measuring lines with gas separators in each pipeline for the supply of oil products, which is economically disadvantageous, since in this case the number of measuring lines equal to the product of the number of products to be filled by the number of filling points is required. So, for example, with a gallery filling of two trains of 36 wagons each, with a nomenclature of loading consisting of 8 products, the number of gas separators and measuring lines, including the necessary piping, will be 72 × 8 = 736. To implement redundancy of the flowmeters of this system with a standard unit design, the number of measuring lines will be 1472. Such a system requires a large investment in construction and operation and is not reliable, since failure of any element of such a system will lead to simple and time-consuming re-composition.

In addition, in the prior art, in accordance with the requirements of manufacturers, flowmeters are typically set so that the flow when passing the flowmeter is directed in a certain way, and therefore requires the appropriate spatial orientation of the flowmeter, which complicates the equipment, imposes additional restrictions on the design of the selection unit and accounting for the shipment of liquid petroleum products and does not allow to reduce the dimensions of the node and make the design of the node more compact (see figure 1), while, as shown in figure 1, cc In order to do that measure each line there is only one flow meter, its failure leads to malfunction of the whole line, requiring repair assembly shipment delayed until its closure. That is, failure of a single flow meter will lead to the inoperability of the entire unit for the selection and accounting of shipment of liquid products, since, for example, when shipment of wagons with a changing composition of wagons by products is shipped, the composition cannot be shipped in the absence of the necessary range of shipped products.

On the other hand, nowadays, increasingly high demands are placed on ensuring the smooth operation of the units for selecting and accounting for the shipment of liquid products, which is manifested in the supply of such units with redundant bulk lines and measuring instruments. In the above example, this also causes at least double the amount of equipment available, including measuring instruments, for selecting and accounting for the shipment of products, i.e. disproportionate material and capital costs, as well as the costs of maintaining such an integrated system, including regular verification whole measurement system.

Based on the foregoing, the objective of the invention is the creation of systems that include various combinations of nodes for selecting and accounting for the shipment of liquid products, which increase the reliability of the supply of liquid products, simplify the design, reduce construction costs, purchase equipment, operate and monitor the equipment in a compact design node.

Another objective of the invention is the creation of systems that include various combinations of nodes for selecting and accounting for the shipment of liquid products, which provides for the possibility of redundant measuring lines to increase the uninterrupted operation of the systems for selecting and accounting for the shipment of liquid products in general.

In the proposed solution, two feed units are combined into one system using piping and an additional bypass standby measuring line. In this case, an additional measuring line can be used to account for the supply of the product through any of the loading lines of two or more supply units integrated into the system, and, in addition, allows cross-reservation of the supply units and power lines of each liquid product dispatch line.

In a first aspect, the present invention relates to a system for selecting and accounting for shipment of liquid products while providing redundancy, comprising

at least two nodes for the selection and accounting of shipment of liquid products, including

a collector connected to at least two supply pipelines for supplying at least one product,

a backup measuring line containing backup measuring means for measuring the flow rate of the product and connected by piping connecting lines having shut-off means to the loading lines of each of the nodes upstream and downstream of the measuring devices located in the loading line of each of the nodes,

moreover, the system for selecting and accounting for the shipment of liquid products is made with the possibility of gravity emptying the collectors and bulk lines of each of the nodes and the backup measurement line through the bulk pipe of at least one of the nodes located downstream of the collectors and the backup measurement line.

Due to the location in the nodes included in the system, measuring instruments after the collector, the number of necessary measuring instruments can be reduced by a number of times, numerically equal to the number of products to be shipped, while ensuring the necessary redundancy. It is advisable if the measuring instrument is configured to determine the parameters of the entire range of shipped liquid products. In this case, at least one measuring device can be used to ship the entire range of liquid products, in particular, light petroleum products.

Preferably, at least one liquid product selection and metering unit used in the system further comprises a gas separator installed in the bulk line and / or in at least one of the supply pipelines in front of the collector.

The function of the gas separator is generally known, while, according to existing requirements, the gas separator is always located in the supply line of liquid petroleum products upstream of the measuring device.

In another expedient embodiment of the nodes for selecting and accounting for the shipment of liquid products, the gas separator is installed in the bulk line downstream of the collector, but upstream of the measuring device, and a bypass line additionally departing from the gas separator, connecting to the bulk line upstream of the measuring device to ensure the conditions of its proper work.

Used in the present description, the terms "upstream" and "downstream" refer to the direction of transportation of the liquid product, starting from the supply pipelines, and ending with a riser, pipe or similar device for loading the product into the consumer's tank.

It is advisable if the gas separator is installed in the bulk pipe downstream of the collector, but upstream of the measuring device, while the bypass line connecting to the bulk pipe downstream of the measuring device further leaves the gas separator. With this arrangement, a particularly quick and possibly complete emptying of the bulk pipe and the collector is ensured, which is essential when changing the type or type of products shipped to ensure that mixing is minimized during their change.

In addition to preventing the product from moving in the main operating modes along the bypass line, in addition to the main line, it can be provided that the bypass line leaving the gas separator is additionally equipped with shut-off means, and the gas separator can be drained by gravity through the filling line when the shut-off means of the specified bypass line are opened.

Additionally, the bypass line extending from the gas separator may be provided with a pump and at least one shut-off means, and shut-off means, in particular, a check valve or shut-off valve, are additionally placed in the main line of the filling line.

In a suitable development variant of the invention, it is provided that the filling line comprises locking means of the filling line downstream and / or upstream of the measuring means.

In general, the nodes for selecting and recording the shipment of liquid products used in the system are made with the possibility of emptying the measuring means by gravity through the bulk pipe.

If necessary, the nodes for selecting and recording the shipment of liquid products can be additionally equipped with one or more air valves.

To ensure a controlled shipment of the product, each filling line contains an adjustable locking means.

In an alternative embodiment of the system, nodes for selecting and accounting for the shipment of liquid products can be used, in which a gas separator is installed in at least one of the supply pipelines, and the bulk line in the section extending from the collector branches into the main line of the bulk line and the bypass line, which are then connected together upstream of the measuring instrument, the bypass line is additionally equipped with a pump, and a shut-off medium is additionally placed in the main line of the bulk pipe There is, in particular, a check valve or a shut-off valve.

The system for selecting and accounting for the shipment of liquid products is performed with the ability to control an automated control system, emergency protection, monitoring and control of loading, containing centralized control stations and a system for collecting, analyzing and storing information. Since such tools are known to specialists, their further specification is not given. However, it should be noted that the control system is equipped with appropriate calculation and control tools and algorithms to ensure that the corresponding locking means are opened to ensure the selection of the shipped product in accordance with the shipment schedule and the shipment task, emptying the bulk pipe and manifold when changing the product, and if necessary, further continuation of the shipment, while controlling the quantity, pressure, temperature, pressure, density and other parameters of the shipment desired product.

The system for selecting and recording the shipment of liquid products can be improved by the fact that the loading lines of the nodes used in it contain locking means regulated by the automatic control system, loading control and emergency protection based on measurements of the product flow by a measuring device in accordance with the product shipment schedule and the shipment task .

To increase the reliability of operation and ensure the uninterrupted operation of individual nodes for selecting and accounting for the shipment of liquid products included in the system, in case of measuring device failures, at least one of the nodes can additionally provide one or more redundant measurement lines connected to the bulk pipe upstream and downstream of the measuring device located in the bulk pipe, and the backup line of measurement contains additional measuring means for measuring the flow rate of the product and shut-off facilities.

In a second aspect, the present invention relates to an embodiment of a system for selecting and accounting for shipment of liquid products while providing redundancy, comprising

In this embodiment, a particularly quick emptying of the bulk pipe and manifold is ensured when changing products. It is advisable if both the collector and the line of change and the bulk pipe of the nodes are located mostly downward, in particular, approach the vertical.

The nodes for selecting and recording liquid product shipment used in this embodiment of the system further comprise a gas separator installed in the measurement line and / or in at least one of the supply pipelines. When installing a gas separator in the measuring line, it is advisable that it is located with minimizing the distances of the annular joints, which allows for a high emptying rate.

It is particularly preferable if the gas separator is installed in the upper part of the measuring line upstream of the measuring means, while the bypass line connecting to the collector and provided with bypass line locking means further departs from the gas separator.

In the nodes of the selection and accounting of the shipment of liquid products, it may be provided that the measurement line contains locking means downstream and / or upstream of the measuring means. Due to this embodiment, it is possible to service the measuring line and / or replace the measuring means.

The nodes for selecting and accounting for the shipment of liquid products used in the system according to the second aspect of the invention are also adapted to empty the measuring means by gravity through the bulk pipe.

If necessary, such units, in particular a collector or a measurement line, are additionally equipped with one or more air valves.

The nodes can also be equipped with adjustable locking means, a control system, emergency protection, monitoring and control of filling, as well as performed with redundant measurement lines, as disclosed with reference to the first aspect of the present invention.

In a third aspect of the present invention, a system for selecting and accounting for shipment of liquid products with redundancy comprises

at least two nodes for the selection and accounting of shipment of liquid products, including

a collector connected to at least two supply pipelines for supplying at least one product, wherein the collector has an upper end and a lower end,

locking means of pipelines, providing opening and closing of the supply pipelines for supplying at least one product to the collector,

a backup measuring line containing backup measuring means for measuring the flow rate of the product and connected by piping connecting lines having locking means with measuring lines of each of the nodes upstream and downstream of the measuring means placed in the measuring line of each of the nodes,

moreover, the system for selecting and recording the shipment of liquid products is made with the possibility of gravity emptying the collectors, measurement lines, indicated bypass lines and bulk lines of each of the nodes and the backup measurement line through the lowering bulk line at a lower position relative to the collectors, measuring lines and bypass lines and the backup measurement line least one of the nodes.

In this version of the system, nodes are used in which the shipped product enters the measuring instrument in the form of an upward flow, which allows the use of measuring instruments that require a certain orientation in space.

It is advisable if the measuring device is placed higher relative to the connection of the measuring line with the lower part of the collector.

At least one liquid product selection and metering unit used in the system according to this embodiment also further comprises a gas separator installed in the measurement line and / or in at least one of the supply pipelines.

For the third aspect of the invention, the variations and improvements disclosed above with respect to the first and second aspects are also applicable.

In General, the effect of the present invention is to increase reliability, as well as reducing structural costs and maintenance costs, due to the reduction in the number of elements, the failure of each of which leads to the failure of the entire system, increasing the reliability of the entire layout in a proportional number of times, reducing construction costs, equipment purchase, operation, verification, etc.

In addition, in the inventive system according to the invention, the disadvantages of the design of systems and delivery units known from the prior art are eliminated, in which there is no redundancy of the measuring lines and it is impossible to use operable trunk lines of the branch of one node to load the branches of the second node in the event of the failure of any of its elements while maintaining the constructive possibility of emptying all highways when changing products.

As used herein, the term “bulk pipe” in the context of the present invention refers to a line for transporting liquid products from a collector to a product filling device, for example, a bulk pipe. Unloading line, unless expressly specified in a particular embodiment of the invention, comprises shut-off, measuring and / or pumping means known to those skilled in the art for supplying liquid products to the inlet pipe.

The term "collector" in the present invention is used in the traditional sense, characterizing the portion of the liquid product supply line, combining several supply pipelines, including shut-off devices and preceding the said bulk line.

Both the collector and the bulk pipe are located mainly in a descending manner, that is, with a change in height position, due to which their gravitational emptying is ensured by gravity.

The term "bypass line" refers to the bypass section of the pipeline, providing the transportation of fluid bypassing one or more measuring, shut-off or other elements. For example, a gas separator bypass line should be considered as a line allowing fluid to be transported bypassing the gas separator.

The measuring line is generally formed by a section of the supply line on which the quantity, speed, pressure and / or other parameters of the flow of the supplied liquid product are measured and taken into account. The measurement line, as is known to those skilled in the art, contains one or more measuring means, as well as locking means, which provide maintenance of the measuring line or its locking when emptying the supply line or when using an appropriately assigned bypass line.

The following description of some embodiments of the invention is given in order to clarify the principles of the invention and its practical applicability, thereby allowing other specialists to understand the invention in various embodiments and with various modifications that are suitable for the particular intended application. This description is not intended to be exhaustive or limiting the invention to the exact described embodiments.

Further, in the subsequent drawings, elements that are not mandatory and / or not essential for the implementation of the present invention, but at the same time inherent in conventional solutions in the art, are not reflected to facilitate the presentation.

In the figures shown, like elements are denoted by the same reference numerals.

As shown in figure 2, the node selection and accounting for shipment of liquid products in one embodiment includes a supply pipe 3 included in the collector 1, as well as the corresponding locking means 4 of the pipelines. The collector 1 is made with an air valve 10, and directly to the collector 1 there is a bulk line 2 containing a gas separator 5, a bypass line 8 of the gas separator with locking means 9, measuring means 6, in particular a flow meter, as well as an adjustable locking means 7. Accordingly, the means 6 measurements and a gas separator 5 are structurally located after the collector 1 on the product supply line to the filling device. Moreover, to avoid mixing when changing products, the entire bulk line 2 after collector 1, including measuring means 6 and gas separator 5, has a downward design that allows them to be naturally emptied at the end of the filling process before changing products. At the gas separator 5, a bypass line 8 is additionally provided, which connects with the bulk line 2 upstream of the measuring means 6, with the locking means 9, which allows you to quickly complete the complete discharge of the gas separator 5 and, at the same time, prevent the product from flowing along the bypass line during the main shipment since the bypass line closure, such as a bypass valve, only opens after closing the valve on the manifold before changing products.

The shown node selection and accounting for shipment of liquid products works as follows. In the initial state, all locking means 4, 7, 9 are closed. The bulk line 2 after collector 1 is exempted from the product. If it is necessary to ship the product, one of the locking means 4 is opened for the liquid product from the supply pipe 3 to enter the manifold 1. The product completely fills the bulk pipe 2 from the adjustable locking means 7 to the air valve. In this case, the air is forced out through the air valve 10. The adjustable locking means 7, by means of appropriate control, opens by the amount necessary to ensure a given supply level. The selected product passes through the measuring means 6 and enters the pipelines of shipment. Upon reaching a predetermined loading level and there is information about product change for subsequent filling, the locking means 4 closes, the air valve 10 opens, the locking means 9 of the bypass line 8 opens to drain the product from the gas separator 5, and the product releases gravity line 2 by gravity collector 1, while measuring means 6 measures the amount of product when emptied. At the end of the draining process, all the locking means 7, 9 are closed, and the system goes into standby mode for the subsequent pouring. In the event that product change during subsequent filling is not planned, at the end of the current filling the adjustable locking means 7 are closed and the supply line is emptied after it, and the filling line 2 between the collector 1 and the adjustable locking means 7 remains filled until the next loading cycle, there is no filling before the next filling.

Using the claimed solution will reduce the number of measuring instruments or measuring lines on the racks of automobile, railway clock or gallery loading, to account for the shipment of more than one type of oil products, reduce investment in the construction of flyovers and their operation, will increase the reliability of the system.

Figure 3 shows the node for the selection and accounting of shipment of liquid products, in which, in contrast to the solution of figure 2, the gas separators 5 are located in the supply piping 3 in front of the shut-off means 4 of the pipelines, in addition, the bulk line contains the shut-off means 11 of the bulk line, allowing maintenance of the filling line and / or measuring means 6, as well as an adjustable locking means 7, controlled to ensure a given product shipment. This solution is characterized by a faster emptying of the bulk pipe 2, while the corresponding gas separators 5 may remain filled with the product.

In the embodiment shown in FIG. 4, the selection and metering unit for dispatching liquid products includes inlet pipelines 3 included in the manifold 1, as well as corresponding shutoff means 4 of the pipelines. The collector 1 is made with an air valve 10, and directly to the collector 1 there is a bulk line 2 containing a gas separator 5, a bypass line 8 of the gas separator with shut-off means 9, measuring means 6, in particular a flow meter, as well as an adjustable shut-off means 7. To ensure maintenance measuring means 6, locking means 11 of the filling line are provided upstream and downstream of the measuring means 6, while the bypass line 8 is connected to the loading line 2 downstream of the means of change 6 and corresponding locking means 11. In the shown embodiment, the measuring means 6 and the gas separator 5 are also structurally located after the collector 1 on the product supply line to the filling device. Moreover, to avoid mixing when changing products, the entire bulk line 2 after collector 1, including measuring means 6 and gas separator 5, has a downward design that allows them to be naturally emptied at the end of the filling process before changing products. The gas separator 5 is additionally provided with a bypass line 8 with a locking means 9, which allows you to quickly complete the complete emptying of the gas separator 5. The assembly for selecting and recording liquid products shipment shown in Fig. 4 works as follows.

Initially, all elements of the supply unit are exempted from the product, including manifold 1, gas separator 5, and bulk line 2. If product is needed to be shipped, shut-off means 4 of pipeline 3 are opened, as well as shut-off means 11 of bulk line 2. The product fills the entire bulk line 2 to an adjustable shut-off means 7, while the shut-off means 9 of the bypass line 8 is also open while filling the filling line 2, and all air is expelled through the air valve 10. At the end of filling the filling line 2, the locking means 9 is closed, and the adjustable locking means 7 is opened by the amount necessary to ensure a given supply level. The selected product passes through the gas separator 5 of the measuring device 6 and is supplied for shipment. Upon reaching a predetermined filling level and the required product change for subsequent filling, the locking means 4 of the pipe 3 is closed, the air valve 10 is opened, as well as the locking means 9, so that the product contained in the manifold 1 and the gas separator 5 flows through the bypass line 8, adjustable locking means 7 and further to the filler pipe, while the measuring means 6 is also empty. In this case, the emptying takes place in two ways 2, 8, which ensures high completeness of emptying. At the end of the drainage process, all locking means 7, 9, 11 are closed, and the system goes into standby mode for subsequent filling. In the event that product change during subsequent filling is not planned, at the end of the current filling the adjustable locking means 7 and the locking means 4 are closed, and the supply line is emptied only after the adjustable locking means 7, and the filling line 2 remains filled until the next filling cycle .

Using the solution will reduce the time and ensure high completeness of emptying the highways on the racks of automobile, railway clock or gallery loading, to account for the shipment of more than one type of oil product, with two or more loading points, while maintaining the requirement that the products should not be mixed when changing them.

In the embodiment shown in FIG. 5, the selection and metering unit for dispatching liquid products includes inlet pipelines 3 included in the manifold 1, as well as corresponding shutoff means 4 of the pipelines. The collector 1 is made with an air valve 10, and directly to the collector 1 there is a bulk line 2 containing a gas separator 5, a bypass line 8 connected to the bulk line 2 upstream of the measuring means 6, and also an adjustable locking means 7. Accordingly, means 6 measurements and gas separator 5 are structurally located after the collector 1 on the product supply line to the filling device. Moreover, to avoid mixing when changing products, the entire bulk line 2 after collector 1, including measuring means 6 and gas separator 5, has a downward design that allows them to be naturally emptied at the end of the filling process before changing products.

The gas separator 5 is additionally provided with a bypass line 8 with locking means 9, which allows you to quickly complete the complete emptying of the gas separator 5, and to speed up the emptying and maintaining the measuring means 6 in the bulk line 2 of excessive pressure, the pump 12 is additionally included in the bypass line 8, and in the bulk the line 2 includes a non-return valve 13 or other device restricting the flow of the product in the opposite direction of the bulk pipe 2 with the pump running. In general, the operation of the unit is similar to that described with reference to figure 2, while the pump 12 is turned on simultaneously with the opening of the locking means 3, and at the same time, the check valve 13 or other device is closed, restricting the flow of product in the opposite direction of the bulk pipe 2.

As shown in Fig.6, the above option can be modified in that the gas separators are located in front of the manifold 1. In this case, there is no need to empty the gas separators when changing the product. Using the solution of Fig.6 will significantly reduce the time of emptying the bulk pipe 2, will stabilize the flow rate and pressure of the product entering the measuring means 6.

7 shows another embodiment of a unit for selecting and accounting for the shipment of liquid products in one embodiment, which includes inlet pipes 3 included in the collector 1, as well as the corresponding shut-off means 4 of the pipelines, the lower end of the collector 1 being provided with shut-off means 16 of the collector, directly adjacent to the bulk pipe 2 containing an adjustable locking means 7.

At the upper end of the manifold, a measuring line 15 is connected, comprising a gas separator 5, which has a bypass line 8 with shut-off means 9 connected to the collector 1. A measuring line 6 is also provided in the measuring line 15, in particular a flow meter, as well as shut-off means 14 of the line measuring upstream and downstream of the measuring means 6.

In the shown embodiment, the collector, the measurement line 15 and the bulk pipe 2 have a downward design that allows them to be naturally emptied at the end of the filling process before changing products.

The gas separator 5 is located near the upper part of the collector 1, above the measuring means 6.

Shown in Fig.7 node selection and accounting for shipment of liquid products works as follows.

In the initial state, all locking means 4, 7, 9, 14 and 16 are closed. The components of the supply unit, including the collector 1, the gas separator 5, the measurement line 15, the bypass line 8 and the filling line 2, are exempted from the product.

If it is necessary to ship the product, the locking means 4, the locking means 9 of the bypass line 8, the locking means 14 of the measuring line and the locking means 16 of the manifold are opened. The product fills the entire supply line from the adjustable shut-off means 7, displacing air through the air valve 10. Upon completion of filling, the shut-off means 9 of the bypass line 8 and the air valve 10 closes, and the adjustable shut-off means 7 opens by the amount necessary to ensure a given supply level. The selected product passes through the gas separator 5, the measuring line 15 and enters the pipelines of shipment, while using the measuring means 6, the metering parameters of the product are recorded and monitored.

Upon reaching a predetermined filling level and the required product change for subsequent filling, the locking means 4 is closed, the air valve 10 and the locking means 9 of the bypass line 8 are opened, so that the product, under the action of gravity, releases the elements of the unit for selecting and accounting for the shipment of liquid products, while emptying goes through the bulk pipe 2 in two parallel lines: one is formed by a measurement line 15, the second - by a collector 1 with shut-off means 16. At the end of the discharge process, all shut-off means 9, 14, 7, 16 are closed, and the system goes into standby mode for subsequent filling.

In the event that a product change during subsequent filling is not planned, at the end of the current filling the adjustable locking means 7 are closed and the supply line is emptied after the adjustable locking means 7, and the filling line 2 and, if necessary, the measuring line 15, as well as the collector 1 remain filled until the next loading cycle, and filling is not required before loading.

In the presented solution, it is possible to empty the measuring line 15, the collector 1 and the gas separator simultaneously or in any optimal sequence to ensure the necessary emptying.

The product discharged from the mains can be taken into account by calibrating the volume of emptied mains and adding the latter to the shipped quantities.

The solution shown in Fig. 7 makes it possible to reduce the vertical length of the unit, the time of product discharge from it on the ramps of automobile, railway clock or gallery loading, to account for the shipment of more than one type of oil product, with two or more filling points, while maintaining the requirement that the products should not be mixed when they are mixed shift.

The embodiment described above can be modified in that the gas separators 5 are located in front of the collector (see Fig. 8), thereby eliminating the need for emptying the gas separator, while emptying the measurement line 15 and collector 1 can be carried out in any sequence and especially quickly.

An alternative version of the node for the selection and accounting of shipment of liquid products is shown in Fig.9. In the presented embodiment, the arrangement of the measuring means 6 in the measuring line in the upstream section is provided, which further eliminates the delay in the sensitive area of the undissolved gas and air flow meter.

Shown in Fig.9 node selection and accounting for shipment of liquid products includes inlet pipes 3 included in the collector 1, as well as the corresponding locking means 4 of the pipelines. The collector 1 is made with an air valve 10, and the collector is connected to the measurement line 15 and the bypass line 8, which respectively pass into the bulk pipe 2.

The measurement line contains a gas separator 5, as well as the closure means of the measuring line 14 and measuring means 6 located downstream of it. In the embodiment shown in FIG. 9, the measurement line is made in the form of an ascending line that provides upward flow of the product being shipped, and is equipped with an additional air valve 10. A bypass line 8 containing locking means 9 is also adjacent to the junction of the measurement line 15 and the collector 1, and connecting to the bulk highway 2.

Moreover, to avoid mixing when changing products, the measuring line 15 and collector 1 have a downward design that allows them to be naturally emptied at the end of the filling process before changing products.

Shown in Fig.9 node selection and accounting for shipment of liquid products works as follows.

In the initial state, all locking means 4, 7, 9, 14 are closed, and all elements of the assembly are freed from the shipped product.

If it is necessary to ship the product, they are filled with the product, for which the locking means 9 of the bypass line 8, the locking means 14 of the measuring line 15, and the locking means 4 are opened. The product being shipped fills the selection and metering unit for shipment of liquid products to an adjustable locking means 7, when this air is displaced through the air valves 10.

Upon completion of the filling, the locking means 9 of the bypass line 8 is closed, and the adjustable locking means 7 is opened by the amount necessary to ensure a given supply level. The selected product passes through a gas separator 5, a measurement line 15, an adjustable locking means 7 and enters the shipment pipelines.

Upon reaching a predetermined filling level and the required product change for subsequent filling, the locking means 4 is closed, the air valves 10 are opened, as well as the locking means 9 of the bypass line 8, and the product being shipped under the action of gravity releases all the elements of the unit for selecting and recording the shipment of liquid products.

Particularly fast and complete emptying of the unit is achieved due to the fact that it is carried out through two lines formed respectively by measurement line 15 and bypass line 8.

At the end of the emptying process, all the locking means 7, 9, 14 are closed, and the system goes into standby mode for subsequent filling. If it is not planned to change the product during subsequent filling, at the end of the current filling the adjustable locking means 7 are closed, and if necessary, the locking means 4, and the supply line is made only after the adjustable locking means 7, accordingly, there is no need to fill the elements of the selection unit and accounting for the shipment of liquid products before performing subsequent loading.

Using the solution will improve the accuracy of measurements by eliminating the delay of undissolved air and gases in the sensitive zone of the measuring unit 6 for selecting and recording the shipment of liquid products for commercial metering of the shipped product on racks of automobile, railway clock or gallery loading, to account for the shipment of more than one type of oil product, with two or more filling points while maintaining the requirement of inadmissibility of mixing products when changing them.

The embodiment described above can be modified in that the gas separators 5 are located in front of the collector (see FIG. 10), thereby eliminating the need for emptying the gas separator, while emptying the measurement line 15 and the collector 1 can be carried out in any sequence and especially quickly.

11 shows an alternative embodiment of a unit for selecting and accounting for shipment of liquid products, in which the bulk pipe 2 contains a backup line 17 measuring connected to the bulk pipe upstream and downstream of the means 6 of the measurement, while the bypass backup line 17 of the measurement is activated by opening locking means 18 of the bypass backup measuring line 17 when closing the locking means 11 of the bulk pipe 2. It is also possible that the locking means 11 and 18 are open at the same time. In this case, the measurement of the parameters of the shipped liquid product is carried out both by means 6 of the measurement of the bulk pipe 2, and by means 6 of the measurement of the bypass backup line 17 of the measurement. Otherwise, the operation of the unit for selecting and accounting for the shipment of liquid products of Fig. 11 and its elements corresponds to the above description.

12, one of the options is shown enlarged showing how a standby measuring line can be placed in the system for selecting and accounting for shipment of liquid products with provision for redundancy, and its connections with sections of nodes for selecting and accounting for shipment of liquid products combined into a system are shown. The backup measuring line 17 contains backup measuring means 6 for measuring the flow rate of the product and is connected by piping connecting lines 19 having locking means 18 to the bulk lines and / or measuring lines of each of the nodes integrated into the system, upstream and downstream of the means measurements placed in the bulk line and / or measurement line of each node. As shown, the standby measuring line is also provided with an air valve 10. A similar connecting unit of the standby measuring line can be combined with at least two of any of the above nodes for selecting and recording the shipment of liquid products. Preferably, if the branches of the system are formed by nodes having the same or similar design.

On Fig presents an example of a system containing two nodes of the selection and accounting of shipment of liquid products, as well as a backup measurement line. A variant is shown in which said system comprises two nodes of FIG. 2, but in principle a suitable combination of any of the nodes mentioned above is possible. In general, the operation of the elements of the nodes for selecting and accounting for the shipment of liquid products corresponds to the above description, while by closing or opening the corresponding locking means 18 of the bypass standby line 17 of the measurement, the bypass standby line 17 of the measurement is connected to the right or left node of the selection and accounting of shipment of liquid products, shown in FIG. 13. Due to this embodiment, a simple design of the system for selecting and recording the shipment of liquid products is provided, comprising at least two nodes for selecting and accounting for the shipment of liquid products, in which the necessary reservation of measuring instruments and the uninterrupted supply of shipped liquid products, in particular light petroleum products, are achieved.

On Fig presents a second variant of the system containing two nodes of the selection and accounting of the shipment of liquid products, described in detail with reference to figure 5, as well as a backup measurement line connected to each of the nodes.

The third version of the system is shown in Fig. 15, while the design of the nodes for selecting and recording the shipment of liquid products included in the system is described in detail with reference to Fig. 4, and the input and output ends of the backup line are connected, respectively, upstream and downstream flow from measuring instruments of each of these nodes. A feature of this embodiment of the system is that the system lines are released in two ways, which significantly reduces the time and completeness of emptying, since the product contained in the collector and the gas separator flows through the gas separator drain line, the shut-off means of the bulk pipe and then to the bulk pipe, measuring lines of nodes are released through the bulk pipe of the corresponding node, and the backup measuring line is also released through the bulk pipe of one of the nodes.

The fourth version of the system, presented in Fig. 16, contains two nodes for selecting and accounting for the shipment of liquid products according to Fig. 7, the design of which allows to reduce the total vertical length of the device, as well as a backup measurement line connected to the measuring lines of each of these nodes.

In the fifth embodiment of the system shown in Fig. 17, two nodes for selecting and accounting for the shipment of liquid products shown in Fig. 9 are combined, and a backup measurement line is connected by pipelines to the measurement lines of each of the nodes upstream and downstream of the measuring means, placed in the measurement line of each of the nodes.

A feature of the sixth embodiment of the system shown in FIG. 18 is that, unlike previous versions, gas separators are installed in the supply pipelines of the collectors.

Thus, in the inventive system, it is possible to use a backup measurement line in combination with any two or more of the above nodes for selecting and accounting for the shipment of liquid products, and although this is not shown in the drawings, it is also possible to include nodes with different structural designs in the system.

The operation of the system will now be explained with an example of a first embodiment of the system shown in FIG. 13. In the initial state, all locking means, for example, valves, are closed. The bulk line 2 after collector 1 is exempted from the product. If it is necessary to ship the product, one of the valves 4 opens on the supply piping 3 of the collector 1, the shut-off means 7 of the bulk pipe open, and the valve 9 for draining the product from the gas separator opens. The product fills the entire supply line from the control shut-off means 7, for example, the filling line valve 7, to the air valve 10 through which all the air is expelled. Upon completion of filling the lines, the drain valves are closed, the control valve 7 of the bulk pipe is opened by the amount necessary to ensure a given level of flow. The selected product passes through the measuring means 6 in the form of a flow meter 6 and enters the pipelines of shipment. In the event of a failure of the flowmeter 6 of the first assembly, the locking means 11 installed upstream and downstream of the flowmeter, for example, shut-off valves, are closed, the locking means 18 installed in the piping connecting lines of the backup measurement line 17 are opened, and the space between the locking means 18 standby measuring line 17, including a flowmeter 6 installed in the standby measuring line, is filled with a product displacing air through the air valve 10 installed in the standby measuring line . Upon filling the indicated volume, the locking means is opened in the pipeline line 19 connecting the standby measuring line with the bulk line of the first node, as shown in Fig. 13, for example, a shut-off valve, and the product is fed to the bulk pipe through the bulk line 2 of the first node with accounting operations using the backup measuring line 17. Upon reaching the specified level of filling and the required product change for subsequent filling, the shut-off valve 4 of the manifold pipe 3 closes, opens air valves 10, open the drain valve, and the product under the action of gravity releases the collector, the filler line and a spare measuring line, wherein the meter measures the quantity of product during discharge. At the end of the drain process, all valves are closed and the system goes into standby mode for subsequent filling. In the event that a product change during subsequent filling is not planned, the line between the collector and the control valve of the filling line remains filled until the next loading cycle, and its filling is not required before filling.

In the event that the supply of the same type of products is required, their simultaneous loading through the bulk lines of both nodes is permissible. If different types of products are loaded, then loading is possible alternately with emptying and filling the systems before each shift, as already noted. The only difference is that for shipment from the bulk supply line of the first unit, the valves of the connecting line connecting the standby measuring line to the first unit open, for shipment from the second bulk line the valves of the connecting line open connecting the standby measuring line to the second unit are opened. In this case, the selection of the product is performed by opening the corresponding locking means on the manifold pipe of the working unit.

Any of the systems described above for selecting and recording the shipment of liquid products with redundancy and their individual units can be placed in modular rooms, in particular, heated, which further increases the reliability of the equipment.

It is understood that the above description is illustrative, and the claims cover all modifications or alternatives that could be anticipated by a person of ordinary skill in the art.
